Funny how in the US these altezza-style or completely white/clear rear lights are called 'Euro' lights, while these are definitely not used that much here :)

Only now are we starting to see some european cars (eg. BWW 3-Compact series) with this sort of rear lights..

The most you'll see here in europe are usually red-white combinations like the S40 already has. Red for the rear/brake/foglights and white for the reversing lights and indicators (using yellow bulbs).

To stop the yellow bulbs from showing in the rear lights you could replace the standard ones with either Philips Silverstar or Osram Diadem bulbs. These still show yellow when turned on, but have a silver coating when off.

Sorry.. Can't help you with really different rear light clusters. None available here AFAIK..
